Dudemanguy a899e14bcc vo: change vo->driver->wait_events to nanoseconds 
In many cases, this is purely cosmetic because poll still only accepts
microseconds. There's still a gain here however since
pthread_cond_timedwait can take a realtime ts now.

Additionally, 37d6604d70 changed the value
added to timeout_ms in X11 and Wayland to ensure that it would never be
0 and rounded up. This was both incomplete, several other parts of the
player have this same problem like drm, and not really needed. Instead
the MPCLAMP is just adjusted to have a min of 1.
